Abstract

A new and distinct cultivar of Nelumbo plant named ‘Zhongshan Chanyun’, characterized by its upright to somewhat outwardly spreading plant habit; vigorous growth habit; large dark green-colored leaves; freely flowering habit; large purplish pink-colored ball-shaped flowers with numerous petals and petaloids; flowers that are positioned above the foliar plane on moderately strong and erect peduncles; good garden performance and good postproduction longevity.

Description

Botanical designation: Nelumbo nucifera.

Cultivar denomination: ‘Zhongshan Chanyun’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nelumbo plant, botanically known as Nelumbo nucifera, commonly referred to as Sacred or Indian Lotus, and hereinafter referred to by the name ‘Zhongshan Chanyun’.

The new Nelumbo plant is a product of a controlled breeding program conducted by the Inventors in Nanjing, Jiangsu Province, China. The objective of the breeding program is to create new Nelumbo plants that have large double-type flowers with numerous petals and petaloids with attractive coloration.

The new Nelumbo plant originated from a cross-pollination in July, 2017 of Nelumbo nucifera ‘Xiao Lianzuo’, not patented, as the female, or seed, parent with Nelumbo nucifera ‘Xiuqiu’, not patented, as the male, or pollen, parent. The new Nelumbo plant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Nanjing, Jiangsu Province, China in June, 2018.

Asexual reproduction of the new Nelumbo plant by rhizome divisions in a controlled environment in Nanjing, Jiangsu Province, China since March, 2019 has shown that the unique features of this new Nelumbo plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Nelumbo have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Zhongshan Chanyun’. These characteristics in combination distinguish ‘Zhongshan Chanyun’ as a new and distinct Nelumbo plant:

• • 1. Upright to somewhat outwardly spreading plant habit.
  • 2. Vigorous growth habit.
  • 3. Large dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Large purplish pink-colored ball-shaped flowers with numerous petals and petaloids.
  • 6. Flowers are positioned above the foliar plane on moderately strong and erect peduncles.
  • 7. Good garden performance and good postproduction longevity; plants are suitable as garden plants, potted plants and as cut flowers.

Plants of the new Nelumbo differ from plants of the female parent, ‘Xiao Lianzuo’, in the following characteristics:

• • 1. Flowers of plants of the new Nelumbo are ball-shaped whereas flowers of plants of ‘Xiao Lianzuo’ are bowl-shaped.
  • 2. Flowers of plants of the new Nelumbo have twice as many petals than flowers of plants of ‘Xiao Lianzuo’.
  • 3. Stamens of flowers of plants of the new Nelumbo are all transformed into petaloids whereas most of the stamens of flowers of plants of ‘Xiao Lianzuo’ are not transformed into petaloids.
  • 4. Flowers of plants of the new Nelumbo do not produce seeds whereas flowers of plants of ‘Xiao Lianzuo’ produce seeds.
  • 5. Flowers of plants of the new Nelumbo have good postproduction longevity and can be used as cut flowers whereas flowers of plants of ‘Xiao Lianzuo’ are short-lived and not suitable for use as cut flowers.

Plants of the new Nelumbo differ from plants of the male parent, ‘Xiuqiu’, in the following characteristics:

• • 1. Flowers of plants of the new Nelumbo are ball-shaped whereas flowers of plants of ‘Xiuqiu’ are plate-shaped.
  • 2. Flowers of plants of the new Nelumbo have many more petals than flowers of plants of ‘Xiuqiu’.
  • 3. Stamens of flowers of plants of the new Nelumbo are all transformed into petaloids whereas most of the stamens of flowers of plants of ‘Xiuqiu’ are not transformed into petaloids.
  • 4. Flowers of plants of the new Nelumbo do not produce seeds whereas flowers of plants of ‘Xiuqiu’ produce seeds.
  • 5. Flowers of plants of the new Nelumbo have good postproduction longevity and can be used as cut flowers whereas flowers of plants of ‘Xiuqiu’ are short-lived and not suitable for use as cut flowers.

Plants of the new Nelumbo can be compared to plants of Nelumbo nucifera ‘Taoliu Yiyi’, not patented. In side-by-side comparisons plants of the new Nelumbo differ primarily from plants of ‘Taoliu Yiyi’, in the following characteristics:

• • 1. Flowers of plants of the new Nelumbo are ball-shaped whereas flowers of plants of ‘Taoliu Yiyi’ are bowl-shaped.
  • 2. Flowers of plants of the new Nelumbo have many more petals than flowers of plants of ‘Taoliu Yiyi’.
  • 3. Stamens of flowers of plants of the new Nelumbo are all transformed into petaloids whereas most of the stamens of flowers of plants of ‘Taoliu Yiyi’ are not all transformed into petaloids.
  • 4. Flowers of plants of the new Nelumbo have good postproduction longevity and can be used as cut flowers whereas flowers of plants of ‘Taoliu Yiyi’ are short-lived and not suitable for use as cut flowers.
